1turbofocus The coil wire plug in is bad to be bad

DLQ001 Might be worth checking the the rubber insulators between the two manifold pieces. You can see them right below the injectors. I had a #3 misfire. Easy way to check them is with water, you will hear the difference when the water hits the spot. Low water flow and one insulator at a time. Another way if the water doesn't work is with engine cleaner or starting fluid (flammable- be careful). I found mine with water, then used starting fluid to confirm the spot, and again to confirm the repair.
Bought the rubber from the local Goodyear Rubber dealer, got them and had them installed the same day. 2" ID if I remember, 12 inch length is all you will need.

Miss fire #4 after Timing belt

Okay, I've been reading up on the Timing Belt job for months, today I went and did it at my buddies shop. 81K on the car. Did a Timing Belt, Tensioner, idlers, Serp Belt, Serp Tensioner, oil change, fuel filter.

The car is bone stock besides a catback and short ram intake.

We did the job and started the car, miss-fire. Checked the timing 3 more times and it was all correct. Started it again, miss fire. Starting messing with the wires, took #4 on/off and then it started firing and running smooth. GREAT! Put the rest of the car back together.

Go to fire it up to leave, miss fire again. Had to get home at this point so limped it there assuming it was a bad plug wire. Got home and put new wires on it, all 4, and still miss fire. Checked for codes, only had miss fire of #4 which I expected.

The car had aftermarket wires and what looks to be a stock Motorcraft coil.

Did my coil just happen to go bad the same day I did my timing belt? Is there something I'm missing? Also I put new plugs in it 1,000 miles ago and those have been fine (motorcrafts).
